Homicide investigators have ruled out foul play in the death of former That '70S Show star Lisa Robin Kelly.
The actress was found dead at a rehab facility in California last week (14Aug13), just days after voluntarily checking in to battle her addiction issues.
Coroner's reports into Kelly's death are still under seal and no cause of death has been made public.
An autopsy carried out at the weekend proved inconclusive and toxicology results will not be available for weeks.
The actress reportedly died in her sleep.
Many ticket-holders couldn't get into the O2 Arena show on Tuesday night (September 19th) because they didn't bring photo ID to match their booking.
An album re-release, a new song and a documentary mark the singer's legacy this year.
The actor plays the titular hero in the forthcoming adaptation.
